This drawing is of myself with my boss monster from my main Yu-Gi-Oh! deck, Gren Maju Da Eiza. This was made to be my FB cover photo.
To the other side of me is Macro Cosmos, a key card in the deck.
The fire comes from Gren who is a FIRE monster.
For the background I originally tried a space background with stars and planets because that’s what Macro Cosmos does to the field in the anime, and while it looked cool, it didn't really fit for a cover photo. I wanted something lighter to go with my profile picture. So instead I got Dimensional Fissure behind Gren to add to the effect and the D.D. deck, and a clouded sky with the sun shining through, as though summoning Gren ended the darkness or the fight (which it usually does!)
